28
Renal columns
Extensions of the renal cortex deep into the kidney
29
Renal pyramids
Sections of the kidney that consist of medulla
30
Minor Calyx
Connects to a renal papillus; part of the tract of urine outflow
31
Renal papilla
Tips of the renal pyramids
32
Major calynx
Where multiple minor calynx ducts meet and fuse
33
Renal pelvis
Where urine is gathered in the kidney before it is sent to the ureter
34
What is the pathway of urine?
Papilla -> Minor Calyx -> major calyx -> renal pelvis -> ureter -> bladder
35
What is the general pattern of renal arteries and veins?
Arteries usually behind veins
36
What organs are associated with the right kidney?
Right suprarenal gland, liver, descending duodenum, right colic flexure, small intestine
37
What organs are associated with the left kidney?
Left suprarenal gland, stomach, spleen, pancreas, left colic flexure, descending colon, jejunum
38
From medial to lateral, what muscles are associated with the kidneys posteriorally?
Psoas major, quadratus lumborum, transversus abdominus
39
Gerota's fascia
Renal fascia that is fused into a bag and opens medially around the kidneys; continuous around ureters and vessels inferiorally
40
Perinephric fat
Fat inside the renal fascia that immediately surrounds the kidneys
41
Paranephric fat
Fat that lies outside the renal fascia
42
What is the visceral innervation of the kidneys?
Least splanchnic, which arises from T12-L2
43
Ureters
Retroperitoneal muscular tubes that carry urine from the renal pelvis to the bladder
44
What are the 3 constriction joints of the ureters?
Uretopelvic junction, pelvic inlet, entrance to bladder
45
What are the arteries to the ureters?
``` Branches from: Renal arteries Testicular arteries Common iliac artery Internal iliac artery ```
46
What is the visceral innervation of the ureters?
T11-L2
47
What is the referred pain region of the kidneys and ureters?
Groins/flanks, pubic region, and genitals
48
Suprarenal glands
Endocrine lands sitting on the superior poles of the kidneys, located on the perinephric fat
49
What is the right suprarenal gland related to?
Liver, IVC, diaphragm
50
What is the left suprarenal gland related to?
Stomach, pancreas, spleen, diaphragm
51
What are the arteries that supply the suprarenal glands?
Superior artery from the inferior phrenic artery Middle artery from the aorta Inferior artery from the renal arteries
52
Where do the left and right suprarenal vein drain to?
Left: left renal vein Right: IVC directly
53
Suprarenal cortex
Outer layer that secretes mineralocorticoids, glucocorticoids, and sex hormones
54
Suprarenal medulla
Main source of adrenaline and noradrenaline
55
What are the three zones of the suprarenal cortex?

64
Where does lymph from before the diaphragm drain to?
Posterior abdominal lymph nodes
65
What are the layers surrounding the kidneys, from superficial to deep?
Paranephric fat -> Renal fascia -> Perinephric fat
66
What are the layers of smooth muscle in the wall of the bladder?
1) Outer circular 2) Inner longitudinal It's the opposite of the gut tube
67
Where is the suprarenal cortex derived from?
Neural crest cells
68
What is the blow of flood through the suprarenal cortex?
Suprarenal arteries -> capsule -> cortex -> subcapsular plexus -> long cortical artery -> medullary veins -> suprarenal veins -> IVC
